On one'v end of the shaft (D,)'I of this specification, in which; i is a gear (e', e",) which e'ennects with a stud F igur'e 1, is a perspective view of the gear (L), that also connectsV with the gearr front of said machine, and Fig'. f2, an ele- (i) nthe end 'f Lthe shaft (13,),- at the vated view of the back of saine. gear isl a handle z',), which, if moved l'm Said machine consists of the following g to' the right, permits the gear .to turnon the parts, to wit shaft, ifA to the left, the gear is 'in-ade'sta' lst'. (Fig. l). A frame (H, H,) with two gtionary; f f head pins (A, A,) of castiron, orwod, so Upon the other yenilvof the shaft (E,)`, is constructed asI to ber permanent and substan. a gear (f,), which connects with `the 'ear 75 tial.

Y f end of are ratchets 0, 0,), wliichrecfeive 3d. An upper gage (C, R',) being a roller f a rod (8,) made triangular at each end, to (R,) revolving on pivots inserted in afranie *this bearn,if desired, leather to be scarfed, 80 (0,) having its bearings at each end ina or split, ismade fast by aid of the rod and s slide (p), so asl to permit the roller to be gratchet'. The gear (gg) is connected,`.or dis# thrown out from over the knife, byv the leconnected, at pleasure, 'with (f,) 'by V4the ver (A,) each slide supported by spiral ililandle (72,) anda spring.

Converging' each time "lst, by placing the roller inthe under gage, 100 alike, but in diverging passing over one; ]i arallel with the bevel of the knife, it (the fourth more of the circumference at each gage)y having movable bearings, and also, successive step', so that the sixth elevation, equi'distant from its edge, say the thirty `will occupy once and one-halfofthe cirsecond of an inch, whicliis done bythe set cumference in diverging three-eighths" of an screws (a, a, Fig. 2d, 'with hand on (I, 15 inch. The upper ends of the slides (p, 20,) Fig. 1,) turn (D), untilthe upper ends of are fitted to the grooves, so that if placed the slides (p, 20,) are upon the apexes of in a corresponding position, as in Fig. 2, two corresponding elevations, when the gage and motion communicated to the shaft (D,) (C, R,) will be brought to the lowestpoint motion will also be given to the gage (C, R,) of its downward motion, then with set 110 upward, or downward, as the slides apscrews (h, 70,) in head pins (A, A,) bring proach, or recede from the center of the the roller (R,) as near the knlfe as possible and have it revolve without touching it, then with set screws"(o", r,) bring the center of the roll directly over the edge of the knife. As before stated thegelevations in the cams 2),) vary by quarters of their circumference. 1f the gears (e, e, and g,) have a like number of teeth, and the gears (d, and f,) correspond with each other, then (the machine being in motion) will the cams (b, 5,) be turned around once, while the beam G, is turned once. Now if G, is 18 inches in circumference and the slides (p, 29,) at the points of the shortest elevations, nearesty the center of the shaft (1),) then will the gage (C, R,) be forced down once while the beam (G,) is turned one-fourth around, consequently a piece of leather placed beneath the gage and attached to the beam (G,) would be drawn through one-fourth the circumferenceof (G,) or 411i inches. The second set occupying one-half of the circumference would force down the gage while (Gr,) turned one-half around and the leather would be drawn through 9 inches. So on in the same proportion through each set. The v thickness of the leather being the same there will be as many different lengths of scarfs as there are diierent sets of elevations in the cams. c

1n scaring` leathers the gage or roller should be forced down so as to press upon the leathers, and after being scarfed the length ofthe lap will be in proportion to the thickness` of the leather. To scarf leathers with hand on (1,) bring the upper ends of (p, p,) to the lowest point of a particular set of elevations, say second set with hand A on (a) throw out (R,) and place the end of the leather to be scarfed over the edge of the knife, if three-sixteenth of an inch in thickness t inches, if more than three-sixteenth then more than 4, if less then in the same proportion. Set the lever (A) back to its place and with hand on (1,) bring the roll to the leather. See that the handle is moved to the left andthe gear (9,) thrown out of (f,) by the handle (01,) the beam` being at liberty bring the ratchets to the upper side and detach the rod, (S,) fromV them, place the leather across the groove,

then press the rod down into the ratchets `lv which fastens it to the beam.

leather from the beam and with hand on (1,) turn back the shaft, D, to the point started from, and the Vmachine is again ready to cut a lap of the same length. i

longer or shorter.

lWhen other lengths are desired bring the end of the sides to the particular p oint of the cammequired.` The same effect may be produced by placing the shaft (P, Fig. l) in the place of the shaft (D,) and the single cams). These cams are continuous diverging say three-eighths of an inch in passing around and converging suddenly. The

gang of pulleys (m,) willoccupyV the place lof the gear (e, 6,) and a like gang 1n the place of the gear (i) on the shaft (13,) `with their order reversed having the larger oppof site the smaller andso on; these pulleys are connected by a band. To scarf with a ma-f chine arranged in this manner, similarsteps p are taken as with the'other, yexcept that the change in length of scarf is effected by change of band on the pulleys. The gage (C, R,) being forced down once while the c shaft (P,) is turned once, andas thisshaft is turned faster or slower as compared with the motion of (G,) so the scarfs will be "i The same result will' be arrived at by placing a simple cone inthe place of (77%,) the shaftv(1,)beingrin the` c place of (1),) and likewise one at (i) anclf` ,I I,

vconnecting them by band; or the simpleV cams (K, K,) being in the place of (b, '12,)

a change in the length ofthe scarfs may be permit the cams `to remainstationary, while the leather is passing'between the knife and gage, the camsv having been brought' tosuch 1 a point on the slides as to leavethe leather c of the required thickness. f 1 herebyv claim as new,

- The method of cutting' or by any mechanical methodl with the moeffected bychange of gear` at (e, 6,). To operate the above-named machine as a splitter or leveler, it is only necessary to"` bring the handle (i z') tothe right,'so as to` lapsor searng leather by a cam motion single-or spiral,v applied to a gage in such a manner as to gradually vdecrease the thickness of leather' drawn between it and a knife, making it` tapering and of any desired lengthfthis vmotion 'z'. e.
